5 COMPONENTS Description of components XF 95 series - Pressure sensor for monitoring boost pressure. To check the boost pressure, a piezo-pressure sensor is used. This sensor consists of an electronic circuit and a pressure recording element. The pressure recording element records changes in pressure; these changes in pressure are converted into an electrical voltage. The electronic circuit amplifies this voltage to create a usable output signal. 2 Inspection The output voltage can be checked using a multimeter set to the DC voltage range. i 400441 2.6 ALTERNATOR The compact alternator is a lightweight alternator with two internal cooling fans.
The electronic controller also controls pre-excitation of the alternator. The function of the exciter diodes has also been taken over by the controller. The alternator generates high currents in the lower speed range. B connection to terminal 30 on the starter motor 15 power supply after contact S sens connection of the regulator L connection to VIC B connection The alternator has two B+ connections that are connected to each other internally. B+1 is connected to terminal 30 on the starter motor. B+2 is NOT connected. B-- (earth) is connected to the alternator housing. E501373 2-8 200303
